A new Vanderpump Rules cheating scandal is sure to pump you up for Season 11.

On Monday, Dec. 11, Bravo dropped an all-new trailer for the highly-anticipated new season—and it seems Tom Sandoval wasn't the only cast member in the hot seat while filming.

Specifically, in a clip highlighted in the new footage, longtime cast member Tom Schwartz—who was previously married to castmate Katie Maloney—confirmed that he too "cheated" with a member of their cast: "I made out with Scheana [Shay] in Vegas. Nobody knows that."

Understandably, this prompted quite the reaction from co-star Lala Kent, who responded with a simple, "What?"

Same, girl. Same.

Although Schwartz seemingly tried to down play the betrayal, as he told his ex-wife that it was just "one kiss." However, Maloney didn't feel similarly, as she hit back, "My feelings never mattered to you."

Of course, this is just the latest relationship drama to plague the cast of Vanderpump Rules. Earlier this year, fans were rattled when they learned longtime couple Sandoval and Ariana Madix called it quits after the former cheated with their mutual friend and co-star, Rachel "Raquel" Leviss.

Sandoval publicly apologized to Madix, writing in a March Instagram post, "I made mistakes, I was selfish, and made reckless decisions that hurt somebody I love. No one deserves to feel that pain so traumatically and publicly."

He added at the time, "My biggest regret is that I dishonored Ariana. I never meant to disappoint so many people, including our loving families and friends."

The new season returns January 30 at 8/7c on Bravo.
